What is a Merchandise Management System

The aim of a Merchandise Management System is to manage and optimise all of a company’s information flows in the areas of sales, purchasing and warehousing. Information generated using software is used to support the company’s planning and decision-making processes. In order to control flows of commodity within a company, it is necessary to have a Merchandise Management System which maps the movement of goods.

The EDP-based model records every step in the areas of sales and logistics that a commodity goes through on its path from planning by the supplier to delivery to the customer. At the core of a Merchandise Management System is a database containing master data such as items, customers and suppliers as well as movement data for order processing. The entire operational process from procurement to goods issue is controlled from the Merchandise Management System. This includes tasks such as placing orders with the supplier, writing invoices and generating pick lists.

Today’s requirements of a Merchandise Management System often go far beyond just mapping flows of commodity and tend to include controlling functionalities as well as enterprise resource planning (ERP) functionalities. Customer relationship management (CRM) is usually integrated along with the Merchandise Management System into these more comprehensive ERP systems designed to support planning and decision-making processes in the company.


How does a company benefit from the use of a Merchandise Management System?

The use of a Merchandise Management System becomes essential for a company once it reaches a certain size as there is no other way of tackling the arising data volumes. However, the use of appropriate software depends not only on the size of the company, but also on the specific workload associated with routine tasks such as the creation of order confirmations, delivery notes and invoices. If the administrative workload starts to consume too much time, then it is time to replace the homespun office solutions with a professional Merchandise Management System.

A Merchandise Management System offers a company various benefits:

  • Saved time

    Many workflows can be automated.

  • No redundancy

    No redundant data as a result of duplicate entries.

  • Transparency

    Have an accurate overview of current stock levels at all times.

  • Analysis

    Item-specific recording and analysis of all goods in terms of volume and value.

  • Optimisation

    Identify bestsellers and slow-moving items.

This allows sales management to immediately acknowledge which items need to be reordered and which need to be the subject of additional sales campaigns. The warehouse manager knows where stocks of a given item are located and the clerk can view, and if necessary, keep track of the status of order processing in real time.


What are the basic functionalities of a Merchandise Management System?

The basic functionalities of a Merchandise Management System include three interconnected subsystems, which cover the fundamental functions in an operational Merchandise Management System: purchasing, sales and warehousing While the purchasing system deals with the management of offers and ordering, which also includes item planning and complaints, the sales system is all about order processing with offers, orders, delivery notes and invoices. Warehouse management, which is divided into the goods receipt system, goods issue system and stock management, is centred around storage bin management. The Merchandise Management System keeps track of current stock levels of each item and of which storage bins are free as a result of direct booking of incoming and outgoing goods in the warehouse. The software for a Merchandise Management System also contains various interfaces which can be used to provide a connection with other systems, for example accounting.


What is a web-based Merchandise Management System?

A web-based Merchandise Management System features a user interface which can be operated via an Internet browser. This operating concept helps most users get to grips with the application very quickly. The application can be operated on various devices (PC, notebook, tablet, smartphone) and Internet browsers. The approval rate among users is generally very high.


What is ERP software

ERP (enterprise resource planning) software has the same goal as a Merchandise Management System. It controls a company’s business processes with the aim of optimising the information processes. Typically speaking, an ERP system also covers other areas such as human resource management, financial accounting, asset accounting, etc.

The advantages of cloud-based Merchandise Management software

In addition to professional support, you also benefit from continuous further development, updates and added functions. You no longer need to operate and maintain your own servers, which allows you to focus on your core business while also minimising your costs and workload.

With more and more business processes taking place on mobile devices, a cloud-based Merchandise Management System can represent an ideal solution for many companies. Business processes can be controlled anywhere, at any time. Access to master data such as items and customers via the cloud no longer requires any inconvenient network solutions or installation of ERP software – all you need is Internet access and browser software, which are available on all stationary and mobile devices nowadays.

Authorised users only need to enter a password to gain access, after which they can immediately start working with the cloud-based Merchandise Management System. Aside from the practical advantages of a cloud-based system, there are also economic arguments in favour of its implementation. A cloud-based Merchandise Management System allows you to avoid the significant costs associated with the maintenance and management of servers and software.
